Seattle travelers can book $999 roundtrip fares to Athens or Paris starting now, after Alaska Airlines announced Thursday, Aug. 20, that it will launch both seasonal nonstop routes from Sea-Tac in May 2027 on Boeing 787-9 Dreamliners.

The Athens route, launching May 12, 2027, will be Alaska's longest flight ever at 6,181 miles and the only nonstop service between the U.S. West Coast and Greece's capital. It will operate three times weekly through October. The Paris route begins May 25, 2027, running five times weekly through October, according to Alaska Airlines.

Introductory roundtrip economy fares start at $999, available through Wednesday, Aug. 26. Business class suites run approximately $6,795 roundtrip.

"We fly where our guests aspire to go, and Athens and Paris have been high on that list for years," Alaska Airlines CEO Ben Minicucci said in the announcement. "This global growth is possible because of the remarkable people across our airline who take care of our guests and deliver safe and reliable operations."

The additions bring Alaska's intercontinental network from Seattle to seven destinations, joining London, Rome, Reykjavik, Seoul and Tokyo. The airline says it plans to reach at least 12 long-haul routes from Seattle by 2030.

On the Paris route, Alaska will compete directly with Delta Air Lines, which operates daily service, and Air France, which flies the route five times weekly. Paris was Seattle's third-largest European market in 2025, generating roughly 108,500 two-way passengers, according to Aviation Week. The Seattle-Athens market is smaller but grew 21.8% year over year in 2025, reaching about 35,600 passengers.

The Port of Seattle said the new routes will push Sea-Tac's overall international nonstop services to 66. Port Commission President Ryan Calkins called Athens "one of our largest unserved European markets."

Alaska entered the transatlantic market only in April 2026 with flights to Rome, London and Reykjavik. The carrier holds an 11.4% share of Seattle-Europe departing seats this summer, making it the second-largest European operator at Sea-Tac behind Delta.

The expansion comes one day after a report that Alaska's 787 flight attendants called the long-haul service model "unsustainable" and are pushing for more crew or reduced onboard service.
